Did this suddenly start happening if so can you recall anything you did prior to it's start [adding hardware, software or somethin of the sort], well if it started from day one of your computer purchase then thats also another case, are you sure about your power stability I don't know about that side but this side, we lost a few sales cos we didn't consider advising people to have surge protector.
Also don't give up on looking from other places for help Good luck.
